"illegal operation" error message #27

Never seen that before except in a meme. Are you getting any other info aside from the message, any stack trace? The main thing I'd want to find out is which line of code is causing that problems. In the I'll also have a go in a fresh VM to see if something has changed in recent releases of some library. I'm assuming you're having the problem with Google Calendar setup. |

not clear where to find the log. Changed to debug
if i run ./run.sh under calendar info it prints

./run.sh: line 14: 610 Illegal instruction python3

problems.
In the env.sh you can set export LOG_LEVEL=DEBUG and that should
hopefully show a bit more info about what's happening just before the error
occurs.

Oh illegal instruction, that is an important distinction. That's indicating that your python3 installation is not compatible with your hardware. For example it could be an x64 python trying to run on an ARM raspberry pi. What os did you install, and did you do any special steps to install anything else? |

installed it all through command line . had a few issues with some packages in the instructions being depreciated and found newer versions . let me try to reinstall tomorrow.

hey,
use the full image (2021-10-30-raspios-bullseye-armhf-full) and went
through the install guide again. I got the screen-calendar.py to work now.
I also got the google auth set-up.
I did ran into another "pickle" with the generation of the png file. Any
suggestions here?

it’s definitely connecting to the calendar.
it’s a copy of my main calendar where all events are called ‘meeting’. it’s showing 4 ‘meetings’ on the display with the dates but no time !
i don’t understand enough on the google calendar formats in the scripts to see where it might throw an issue. when i run the script it prints exactly what it then shows on the display. ( so it doesn’t look like it’s an inkscape issue on my end with the updates i managed to do)

Yeah it won't update right away, there's a cache file (otherwise you'll hit a rate limit and get blocked). If you delete the calendar.pickle file, then the code should get the meetings fresh from Google Calendar. |
|
I've been able to recreate the 'illegal operation' error. It's very odd. I did a brand new card, flashed Raspberry Pi OS Lite. Installed things. And then I started getting 'illegal operation' on normal commands, not just related to this project. Just running I'll adjust instructions in the documentation as well, to includ pigpiod. And see if there's a simpler way to do some of the steps. |

Good news. Well it's probably a bit late for you so it's "OK News". I've redone the instructions with Raspberry Pi OS. It's muuuuuch simpler now. The setup section is much simpler now. If you do decide to get latest you'll want to rerun the dependencies instructions but it should be shorter this time. |

so.. re-imaged and followed the new instructions, got:

I've redid the instructions with Raspberry Pi OS. It's muuuuuch simpler
now. pigpio is already available via apt, so there's no more make
instructions required, I've removed a bunch of unused dependencies. I've
also replaced inkscape with cairosvg as well so need for the fonts
workaround.
The setup section
<https://github.com/mendhak/waveshare-epaper-display#setup-dependencies>
is much simpler now.

I've reflashed about 10-15 times today and only got that problem once. 😞 I really think this has something to do with the Raspberry Pi Bullseye image. I don't know if it makes a difference, you could try using the Raspberry Pi imager here: https://www.raspberrypi.com/software/
When you open this software press Ctrl+Shift+X and it will open an advanced menu where you can enable SSH and set a username password and enable WIFI too. |

that worked! use balena etcher before

@crazy-raptor in case you run into the error again I found the solution. I've also updated the instructions in the README to download the fixed package version so that should take care of future installers. |

thanks for looking into this !
saw another user mentioning smaller screens. would be great to collect
versions for those ( eg just the next meetings ) also . eg for something
like this
https://www.waveshare.com/product/displays/e-paper/2.13inch-e-paper-b.htm
to work with a pi zero w . I might get one to try something like this

That's a good idea and I think it's not too difficult. Would appreciate if you did that, share the SVG. In the coding side it would be a matter of letting the user specify some environment variable, which causes that 'calendar only' SVG to be picked. And specifying the dimensions required for the output screen |

have you ever looked into the raspberry pico ? mentions it runs micropython
?

I think I've heard of it but never looked into it. It seems interesting in that it would only run the application you put on it, no OS extras. I'm not familiar with how microcontroller types would be set up. I'm guessing for a project like this, you'd need to find an eink display for it + networking module + battery module. |

started a fresh install and when I get try to run python3 screen-calendar-get.py I get a return that just says "illegal operation"
worked through the installation guide, used a fresh raspberry pi image on a pi zero w (got it previously to work with the outlook calendar but wanted to try the google one (got the credentials.json file made and in the waveshare directory)
let me know if you seen this before and what other info is needed?
